Such a wrap film carton 1 includes a front plate 11, a bottom plate 12, a rear plate 13, and a lid plate 14 that are connected to each other. Further, a front panel 15a is connected to the cover plate 14, and the front panel 15a is connected to the lid cover piece (fixed panel) 15 connected to the cover plate 14 and the cover cover piece 15 through a cut line 23 and the front panel 15a. And an unsealing piece (peeling panel) bonded to the plate 11.

  Also, a varnish application region 11a is formed on the entire surface of the front plate 11 on the front panel 15a side, where the peeling varnish is applied by printing, leaving a plurality of adhesive regions 25. In this case, each adhesive region 25 is surrounded by a circular half-cut portion (half-cut line) 25c in which only the surface is cut (FIG. 4). Each adhesive region 25 has a varnish application part 25b to which a peeling varnish is applied, and a varnish non-application part 25a to which a peeling varnish is not applied, and the unsealed piece 16 is attached to the front plate 11 in the varnish non-application part 25a. An adhesive to be bonded is applied.

  In FIG. 4, each adhesive region 25 is surrounded by a circular half-cut portion 25c, and has four rectangular varnish non-application portions 25a and a varnish application portion 25b provided between the varnish non-application portions 25a. However, the shape of the varnish non-applied portion 25 in each adhesive region 25 may not be rectangular but may be circular, and the number is not limited to four, and any number of two or more may be used. Can take.

  In FIG. 1, the carton 1 can be opened by peeling off the adhesive region 25 where the front surface of the front plate 11 and the back surface of the opening piece 16 are partially bonded, and cutting off the opening piece 16 from the cut line 23. it can.

Can do. As a result, a necessary amount of the wrap film is drawn from the roll of wrap film accommodated therein, and the wrap film is cut by the cutting blade 26 for use.

  Next, the structure of the wrap film carton 1 will be described in detail with reference to FIG.

  FIG. 2 is a development view of the blank 10 of the wrap film carton 1 of the present invention. In the blank 10, the front plate 11, the bottom plate 12, the rear plate 13, and the lid plate 14 are connected to each other via the broken lines a, b, c. It is connected. A fold piece 17 is connected to the side edge side of the front plate 11 via a fold line e, and a lid cover piece (fixed panel) 15 is connected to the side edge side of the cover plate 14 via a fold line d. An opening piece (peeling panel) 16 is detachably connected to the lid cover piece 15 via a cut line 23. A cutting blade 26 is attached to the back surface of the lid piece 15 along the cut line 23, and after the opening piece 16 is cut off, the blade portion of the cutting blade is exposed to be exposed from a roll of wrap film stored inside. A necessary amount of the wrap film is drawn out, and the wrap film can be cut with the cutting blade 26.

  In addition, the first side piece 18, the side plate 19, the second side plate 20, and the side lid are respectively provided at both end positions of the front plate 11, the bottom plate 12, the rear plate 13, the lid plate 14, and the lid lid piece 15 via a broken line f. A plate 21 and a side lid piece 22 are provided continuously. Further, the side plate 19 may be provided with a pop-out preventing piece 19a. Here, the length of the side plate 19 is substantially the same as the width of the front plate 11 and the rear plate 13, and the length of the first side piece 18 and the second side piece 20 is shorter than the side plate 19. Further, the length of the side cover plate 21 is about half of the length of the side plate 19, and the length of the side cover piece 22 is shorter than the width of the cover plate 14.

In the wrap film carton 1, the cut line 23 can be cut from both directions. The shape of the cut line 23 has a shape that can be cut from both directions. Whereas cutting line of a conventional wrap film carton shown in FIG. 7 (a) is a shape cut from one direction, tear line 23 of the carton wrap film of the present invention shown in FIG. 7 (b) in both directions It has a shape that can be cut off. In the present example, is provided with the oblique line outwardly from both ends of the linear portion, in addition to the present embodiment, for example, as shown in FIG. 7 (c), an outer direction of each generally L-shaped from both ends of the linear portion The shape may be provided.

  As described above, the surface of the front plate 11 is provided with a plurality of adhesion regions 25 surrounded by the half-cut portions 25c as shown in FIG. The half-cut portion 25c can be formed by cutting about half of the paper base material, which is the material of the wrap film carton 1, from the surface.

  Further, the shape of the half-cut portion 25c provided on the front plate 11 is not limited to the above-mentioned circle, and may be, for example, an oval, an ellipse, a rhombus, a hexagon, or the like.

  As described above, the number of the adhesive regions 25 surrounded by the half-cut portions 25c provided on the front plate 11 is not particularly limited. However, before use, the opening piece 16 is fixed to the front plate 11 and does not peel off. And in use, it sets suitably so that the surface layer of the front board 11 may peel in this partial junction part, and opening may become easy.

  Further, the shape of the cutting blade 26 may be U-shaped or V-shaped in addition to the linear shape. In the case of the V-shape, the cutting line 23 is V-shaped, and the position and shape of the bonding region 25 are determined. The positions of the curved portions are arranged at equal intervals on the straight line, but the shapes are different.

  Next, the operation of the present embodiment having such a configuration will be described.

  First, a method for assembling the wrap film carton of the present invention will be described. First, the blank 10 is bent along each of the polygonal lines a, b, c, d, e, and f, the back surface of the folded piece 17 is attached to the back surface of the front plate 11, and then the surface of the second side piece 20 and The carton body 2 of the carton 1 is formed by sandwiching the first side piece 18 between the back surface of the side plate 19 and sticking each contact surface. Moreover, the cover part 3 is formed by sticking the surface of the side cover piece 22 and the back surface of the side cover plate 21.

  The wrap film carton 1 assembled in this way accommodates a roll-shaped wrap film F in the carton body 2. And by the adhesion | attachment area | region 25 of the front board 11, the surface of the front board 11 and the back surface of the opening piece 16 are stuck, and, thereby, the carton 1 is sealed. In that case, the varnish non-application part 25a of the adhesion | attachment area | region and the opening piece 16 are adhere | attached.

  When the carton 1 for wrap film of the present invention is used, as shown in FIG. 1, the opening pieces 16 are separated from the positions of the cut lines 23 by pinching the knobs 27 on both ends of the opening pieces 16. As a result, the paper on the inner surface of the adhesive region 25 in the front plate 11 is delaminated to open the wrap film carton 1. At this time, in the carton 1 for wrap film, the cut line 23 can be cut from both sides, and the opening piece 16 can be opened from both directions. After opening the opening piece 16, the cutting blade 26 is exposed. At the same time, since the roll-shaped wrap film F stored in the carton 1 is also exposed, the wrap film F can be fed out by a necessary amount and cut by the cutting blade 26.

  By the way, the varnish for peeling is applied to the front plate 11 while leaving a plurality of adhesive regions 25 surrounded by the half-cut portions 25c to form varnish application regions 11a, and each adhesive region 25 is a varnish to which an adhesive is applied. It has a non-application part 25a and a varnish application part 25b, which is located between the varnish non-application part 25a and applied with a peeling varnish.

  For this reason, compared with the case where an adhesive is applied to the entire surface of each adhesive region 25, the adhesive strength of each adhesive region 25 is adjusted to prevent delamination of the open piece 16 so that the open piece 16 can be smoothly and reliably moved forward. It can be peeled from the plate 11.

  That is, in the case of the wrap film carton as the comparative example shown in FIGS. 5 and 6, the varnish application region 11a is formed by applying the peeling varnish leaving a plurality of adhesive regions 25 on the entire surface of the front plate 11. . In FIGS. 5 and 6, the adhesive is applied to the entire surface of the adhesive region 25 without applying the peeling varnish to each adhesive region 25.

  5 and 6, when the carton 1 for wrap film is opened, since the adhesive is applied to the entire surface of each bonding region 25, when the opening piece 16 is peeled off from the front plate 11, the opening piece 16 becomes the front plate. It is also conceivable that the unsealed piece 16 is firmly fixed to the opening 11 and delamination occurs in the opening piece 16 itself, so that the opening piece 16 cannot be reliably peeled off from the front plate 11.

  The opening piece 16 of the carton 1 shown in FIG. 5 and FIG. 6 is provided with a notch 24 for easily opening the opening piece 16. Sometimes encouraged.

  On the other hand, according to the present invention, each adhesion region 25 has a plurality of varnish non-application parts 25a provided with an adhesive and a varnish application part 25b positioned between the varnish non-application parts 25a. The adhesive strength in the region 25 is adjusted. For this reason, when peeling the opening piece 16 from the front board 11, the excessive adhesion | attachment between the front board 11 and the opening piece 16 can be suppressed.

  Thus, when the opening piece 16 is peeled off, the bonding region 25 is moved to the opening piece 16 by the half-cut portion 25c of the bonding region 25, or the opening piece 16 is separated from the adhesive of the varnish non-application portion 25a of the bonding region 25. Thus, the opening piece 16 can be easily and reliably peeled from the front plate 11.

  Next, specific examples of the present invention will be described.

Cellulose fiber paper (Rengo, CRC, 400 g / m ² ) was used as the blank 10 for producing the carton 1.

  The punching machine used was SP-130ER manufactured by Bobst, and the pasting machine used SR1000-A1 manufactured by Sun Engineering. At this time, a known emulsion type was used as the adhesive applied to the varnish non-applied portion 25a of the adhesive region 25.

  Thus, the wrap film carton 1 according to the present invention shown in FIGS. 1 to 4 was obtained.

  Similarly, a carton 1 for a wrap film as a comparative example shown in FIGS. 5 and 6 was obtained.

  Next, the opening operation | work was performed with respect to the carton 1 for wrap films by this invention, and the carton 1 for wrap films by a comparative example.

The results are shown in the table below.

  As is clear from Table 1, in the case of the wrap film carton 1 according to the present invention, the unsealed piece 16 was easily and reliably peeled off from the front plate 11 and the carton 1 could be reliably opened. On the other hand, in the case of the wrap film carton 1 according to the comparative example, there was an example in which delamination occurred in the opening piece 16 when the carton 1 was opened, and the opening piece 16 could not be reliably peeled off from the front plate 11.
